As a workaround, a clever 1Passsword user came up with JavaScript code that can be used for a Safari (or other iOS browser) bookmarklet in iOS 5. The bookmarklet will open 1Password and should populate the domain automatically in the Search dialog entry box. In my short time testing this it does work for some login sites, but not all the time. Even if it doesn't populate the site correctly in the search, at least the bookmarklet allows quick access to the 1Password search entry.
Here is the code to paste in the URL section of the bookmark:
javascript:window.location='onepassword://'+window.location.href.substring(window.location.href.indexOf('//')+2)
This will certainly be helpful for me. How about you?
